Elissa, Julie and I have been keeping up with this instead of elliptical time, and it's truly kicking our butts... but we're already seeing serious results. I'm stoked. Weight loss isn't a huge concern of mine, but being healthy and taking care of my body is, and this has been so helpful.
I won't drone on and on about it, but if you're looking for something, I'd seriously consider this as an option. It is quick, basic and thorough. Do some research. ; ) Click on the picture for a shopping list.
